Average Success Rate

Inspection is a fundamental means of achieving software usability. Past research showed that during usability inspection the success rate (percentage of problems detected) of each individual inspector was rather low. We developed perspective-based usability inspection, which divides the large variety of usability issues along different perspectives and focuses each inspection session on one perspective. We conducted a controlled experiment to study its effectiveness, using a post-test only control group experimental design, with 24 professionals as subjects. The control group used heuristic evaluation, which is the most popular technique for usability inspection. The experimental results are that 1) for usability problems covered by each perspective, the inspectors using that perspective had higher success rate than others; 2) for all usability problems, perspective inspectors had higher average success rate than heuristic inspectors; 3) for all usability problems, the union of three perspective inspectors (with one from each perspective) had higher average success rate than the union of three heuristic inspectors.

The study uses qualitative data for exploring twelve principles of animation and quantitative data for the research methodology approach. For qualitative data, ten animators were selected to analyse the twelve principles of animation in three series of selected Indian Folklore Animation using an animation principles checklist. For quantitative data, a pre-test post-test experimental design was used to measure the effectiveness of Indian Folklore Animation using a questionnaire. The questionnaire consists of four scales of Keller’s ARCS Model of Motivation. A total of 108 pupils from three schools was selected as respondents and were assigned into two groups (treatment and control group) consisted of 54 pupils each. Data collected were analysed using descriptive and inference statistics to answer the listed research objectives. Findings show that there are significant differences in mean scores for pre-test and post-test to show that the Indian Folklore gave motivational effects to the pupils. This implies that Indian Folklore Animation could be developed for Indian Folklore appreciations and for fostering good moral values through animation.

Kecemasan adalah kondisi yang sering ditemukan pada anak prasekolah yang mengalami hospitalisasi. Hospitalisasi adalah suatu keadaan yang mengharuskan anak dirawat dirumah sakit untuk mendapatkan pengobatan. Hampir dalam setiap tahap perkembangan usia anak, kecemasan dan ketakutan akan penanganan medis masih menjadi masalah besar dalam pelayanan keperawatan. salah satu metode yang dapat digunakan untuk menurunkan kecemasan anak adalah terapi token ekonomi. Token ekonomi adalah terapi untuk mengubah perilaku dengan menggunakan pemberian reinforcement dan token. Penelitian ini bertujuan untuk mengetahui pengaruh terapi token ekonomi untuk mengurangi tingkat kecemasan anak prasekolah. Penelitian ini dilakukan di RSUP DR. M.Djamil Padang selama 2 bulan mulai dari tanggal 2 Juli s/d 4 September 2019. Penelitian ini menggunakan desain penelitian quasi experimental design dengan pendekatan pre-post test group design with control group. Populasi dalam penelitian ini adalah seluruh anak prasekolah yang mengalami hospitalisasi. Pengambilan sampel dilakukan dengan teknik purposive sampling dimana 68 responden dibagi kedalam kelompok intervensi (n=34) dan kelompok kontrol (n=34). Analisis menggunakan uji Independent Sample T-Test. Hasil penelitian menunjukkan bahwa ada perbedaan tingkat kecemasan anak prasekolah sebelum dan sesudah penerapan token ekonomi pada kelompok intervensi dibanding dengan kelompok kontrol dengan p value = 0.000. Terapi token ekonomi mempunyai pengaruh positif untuk menurunkan tingkat kecemasan pada anak prasekolah yang mengalami hospitalisasi. Penerapan token ekonomi ini direkomendasikan untuk mengatasi kecemasan pada anak usia prasekolah pada pelayanan kesehatan dirumah sakit dan komunitas.
